FAQ

Q1: How can I confirm this piston will fit my Caterpillar C3.4B engine?
A: To ensure perfect fitment, please check the engine serial number (ESN) located on the engine data plate. Compare it against the C3.4B model specification. You should also measure the existing piston diameter and pin bore to verify it matches the OEM size standard. If you have an original part number, such as 8-98023-526-0, please confirm it matches our listing.

Q2: What is the recommended installation procedure for this piston?
A: We recommend installation by a qualified diesel mechanic. Before installation, lubricate the piston pin, ring grooves, and cylinder bore with clean engine oil. Use a proper ring compressor to install the piston assembly into the cylinder liner. Always follow the Caterpillar service manual for the C3.4B engine for specific torque specifications for connecting rod bolts and ring gap orientation.

Q3: Does this piston come with piston rings and a piston pin?
A: This listing is for the piston itself. Piston rings and the piston pin are typically sold separately. We recommend using new rings and a new pin when replacing the piston to ensure a proper seal and prevent premature wear.
